  • Display lines in last 10 minutes with specific pattern in logs

    3 answers



I am using below command to display log data for last 10 mins. It works fine if the month stays same however when month is changed it doesn't show any data.



awk -v d1="$D1" -v d2="$D2" '$0 > d1 && $0 < d2 || $0 ~ d2' /home/user.log


Works fine if,



D1="Aug 1 12:00:00"
D2="Aug 1 12:10:00"


But doesn't show any data if,



D1="Jul 31 11:55:00"
D2="Aug 1 00:05:00"


P.S I am using AIX

I believe that's because it's really comparing the strings, not the dates. When the month changes it breaks the comparison.



Try formatting the date another way, maybe using epoch or numeric date format.



date -d "Jul 31 11:55:00" +%s


outputs 1533063300. Similarly,



date -d "Aug 1 00:05:00" +%s


outputs 1533107100.



Should be an easy comparison from there.

            How many registers does an x86_64 CPU actually have?

            Image
            Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers. What are those registers and how many are there? register x86-64 share | improve this...
